There is no original picture - the joke originates from the signature of a poster named Robowang on alt.toys.transformers back in the days before you whippersnappers had your image macros and your messageboards. It was simply the sentence, "Ramjet likes toast," which has persisted through the ages.

there is a certain flash animation on the internet of Starscream enjoying toast.......among other things. I linked it here once, the occasion being a total absence of commons sense. Just go searching for it on Google.
